Zorluk: KolayHigh Availability and Redundancy Concepts

A network administrator configures a First Hop Redundancy Protocol (FHRP) across two routers to ensure continuous network availability for clients on a local subnet. To enable seamless automated failover if the primary router fails, which address must be specified as the default gateway on the client workstations?

  1. The shared virtual IP (VIP) address assigned to the redundancy groupCevap
  2. B
    The static physical IP address of the active router's LAN interface
  3. C
    The loopback address assigned to the backup standby router
  4. D
    The management IP address of the local Layer 2 access switch

Cevap

The shared virtual IP (VIP) address assigned to the redundancy group
The correct answer specifies using the shared virtual IP address assigned to the redundancy group. First Hop Redundancy Protocols (FHRPs) present a single virtual IP and virtual MAC address to local clients. When clients point their default gateway to this virtual IP, traffic is dynamically forwarded by whichever physical router currently holds the active role.

Adım Adım Çözüm

1
Identify the primary purpose of First Hop Redundancy Protocols (FHRP) such as HSRP or VRRP.
FHRP provides high availability by allowing multiple physical routers to share a single virtual default gateway address.
Client endpoints need a static default gateway setting that remains constant regardless of individual router hardware failures.
2
Determine the proper host network configuration for high availability.
Assign the Virtual IP (VIP) generated by the router redundancy group as the default gateway on all client workstations.
Traffic directed to the VIP is handled by the active router, and if that router fails, the standby router assumes control of the VIP seamlessly.
